To aZZ whom it may concern: l

V Be it known that I, NELSON H. SEELYE, of

Winchester, in the county of Middlesex and State of Massachusetts, haveinvented'an'lm proved Bearing for Shafts'of Machines, of

which the following is a-specification,- referto the accompanying-draw-venoe being had ings.

In machines in which a beam is reciprocated by means of arotating-shaftthe bearin gs of g the shafts are subjected to very severe strains ateach reciprocation of the beam; and the object of my invention is toprovide bearings" for such shafts much better adapted forrthe class ofmachines than those heretofore used. I

My invention consists in the combination,

in a machine-frame having amain member. through which its driving-shaftextends, of-

that shaft, that member provided with a boss integral therewith andhaving a cylindrical interior, a sleeve with a cylindrical exterior. tofit the interior of the boss and a cylindrical interior to fit theshaft, and means to hold the sleeve from moving in the cylindricalinterior of the boss when in use.

In the drawings,gFigure l-is an end eleva-- tion, partly in section, ofa machine'with my improved'bearings. Fig. 2 shows my shaftbearing andsome of the adjacent parts in section, and Fig; 3 is an end View of thetwo part sleeve making a part of my shaft-bearing.

The frame ofthe machine is composed of uprights -F and suitablecross-pieces. Each upright F has a boss F," whose bore is ofconsiderably greater diameter than the main shaft D, and within eachbore is a bearing which is a cylindrical sleeve in two parts'f f (seeFigs. 2 and 3,) which when together fit in the boss F,iand-the innersurfaces of this two-part sleeve form the bearing in-which shaft Drevolves. This-sleeve (shown detached in Fig. 3) is turned on itsexterior to .boss

in boss Fvby the dowel f entering a recess in boss F and by'collars d don the main shaft. ing-fromthe oil-receptacle formed by a space between:the outer surface of the two-part sleeve and the'inner surface of thebore of When the belt-wheel H is'connected with shaft D bythe clutchG,the shaft-D is driven and the beamA reciprocatedas long as thebelt-wheel Hand shaft D are connected, the

strainupon the'bearings'being so-severe that bearings as heretofore madein this class of The 'wick' fisupplies oil to the bearmachines have longgiven much trouble, as

theyare frequently out of order and repairs [are expensive and'notreadily made. This serious defect is almost wholly remedied by myimproved bearings.

The. means for adjusting belt-wheel H, the

mechanism for actuating shipper G tocause firm. contact between clutch Gand belt-wheel H,'and other features of -'.the machine shown in thedrawings are no part of my"prese nt invention, but are describedand-claimedin my application filed- September20,"1QQl;.Se-

'What'lclaimas my invention isf-i In a machine-frame having a'main''member F through which its driving-shaftextends,

the combination of that shaft-{member F pro vided witha boss F integraltherewith and having a cylindrical interior; a sleeve with a cylindricalexterior to fit the interior of the boss F and a cylindrical interiontofit the shaft; and means to hold the sleeve from moving in thecylindrical interior of the boss F when in use substantially such asdescribed.
